Sound support

MP3 is a decoding standard and is not a proprietary anything.  However,
encoding entails some proprietary masks if done the Fraunhofer way.
Fortunately, there are better ways to encode that make use of open masks
(look at LAME which uses a GPL'd perceptual engine).

In any case, my RTEMS-based MP3 player didn't have any sound drivers.
The MP3 stream was sent directly to an off-chip MP3 decoder IC.  Sorry,
Joel, nothing very useful from my side.
